Re: Extended logging / moved mails jumping back

[Martin Müller via dovecot]

did some improvements on the server.

from

dovecot -n
# 2.2.13: /etc/dovecot/dovecot.conf
# OS: Linux 3.16.0-6-amd64 x86_64 Debian 8.11

to

# 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.16 (fed8554)
# OS: Linux 4.9.0-8-amd64 x86_64 Debian 9.8

dovecot is working for days without issues, logging is running to one file
/var/log/mail.dovecot

In the logfile appears
2019-04-19 18:53:54 imap-login: Info: Login: user=,
method=PLAIN, rip=80.75.xx.35, lip=136.xxx.9.172, mpid=28364, TLS,
session=

All 4 different MUAs Thunderbird are logged in the same way. They are
behind a router, so they having the same remote IP.
So I cant differentiate, which MUA causes which event.

Is there a way, to identify which client raise a special event?

Re: Extended logging / moved mails jumping back

Hi!


Now I have to check, if this a Thunderbird-Issue or is this a 
dovecot-issue. For that reason, I will activate the extended logging 
of dovecot.


I cant see such events in the logfiles. Which switch is to turn on to 
log all events?
Or do anyone know the reason for the annoying 
"copy/move-the-mail-back"-issue?


Thank you in advance for all inputs.

regards, martin


You are missing

mail_plugins = $mail_plugins notify mail_log


Thank you - it didnt work for me (yet). But I think there is another 
problem which I have to solve first. I recognised that the maildelivery 
stops after turning on the logging to the three files.


The incomming mails are held in the mailq, in syslog appears

relay=dovecot, delay=0.13, delays=0.07/0/0/0.06, dsn=4.3.0, 
status=deferred (temporary failure. Command output: Can't open log file 
/var/log/mail.dovecot-error: Permission denied )


In /var/log/mail.dovecot-error are lines like
2019-04-14 10:16:18 auth: Warning: auth client 0 disconnected with 1 
pending requests: Connection reset by peer


Here the output of ls -la /var/log/mail.dovecot-error
-rw-r--r-- 1 root root   21259 Apr 14 11:24 /var/log/mail.dovecot-error


If I turn the extended logging off, all works fine.
`postqueue -f` releases all held mails to their boxes.

Any hints for me?


Thank you!

Extended logging / moved mails jumping back

[Martin Müller via dovecot]

Hi!

About 4-6 MUA Thunderbird 60.6.1 are going to connect with dovecot
2.2.13/IMAP (debian 8) and are using the same user/password. This setup
works for years flawless (updated clients and serversoftware).

Since a few weeks there is one major trouble:

I one of the client moves a mail from the inbox to a another IMAP-Folder,
most of the moved mail are moved for the moment. But an unstable period
later, the mails are moved back to the inbox. In rarely cases, the moved
mail is copied (one in the inbox, one in the destinationfolder).

Now I have to check, if this a Thunderbird-Issue or is this a
dovecot-issue. For that reason, I will activate the extended logging of
dovecot.
